Notes:
1. Cooling Performance is rated at 95°F ambient, 80°F entering dry bulb, 67°F entering wet bulb. Gross capacity does not include the effect of fan motor heat. ARI capacity is net and includes the
effect of fan motor heat. Units are suitable for operation to ±20% of nominal cfm. 17½-20 tons are certified in accordance with the Unitary Large Equipment certification program, which is based
on ARI Standard 340/360-93. 25 ton model ratings shown are tested in accordance with ARI Standard 340/360-93.
2. EER is rated at ARI conditions and in accordance with DOE test procedures.
3. Integrated Part Load Value is rated in accordance with ARI Standard 210/240 or 360. Units are rated at 80°F ambient, 80°F entering dry bulb, and 67°F entering wet bulb at ARI rated cfm.
4. Heating Performance limit settings and rating data were established and approved under laboratory test conditions using American National Standards Institute standards
Ratings shown are for elevations up to 2000 feet. For elevations above 2000 feet, ratings should be reduced at the rate of 4% for each 1000 feet above sea level.
5. AFUE and Steady State Efficiency is rated in accordance with DOE test procedures.
6. Sound Rating shown is tested in accordance with ARI Standard 270 or 370.
7. Refrigerant charge is an approximate value. For a more precise value, see unit nameplate and service instructions.
8. An optional 2 inch pleated filter is also available.
